It's not like Doctor Who is new to television. It can afford to take chances, and I am willing to bet the most avid followers of the show are pleased the writers are taking chances with the new companion. I find Bill bright, full of questions, and excited to be around the Doctor.

In the second episode "Smile," Bill brings a sense of humanity to the doctor. She is genuinely concerned about the doctor's lack of feeling for the loss of human life. In his defense, he has been alive for too long to get too worked up over it. It almost harkens back to Mary Poppins, when Mary tells the students that she isn't attached to them. After all, what would happen to her if she loved all the children she took care of.
I am excited to see what other adventures the Doctor and Bill will experience. I am ecstatic to go along for the ride!
